-4' 'Claims. (01. 28753) This invention .relatesto a. handle assemblyand more particularly to a handle assembly for an automobile windowregulator.

It is the object of this invention to produce a handle assembly which isof simple construction, cheap tomanufacture and easily assembled.

In particular, it is the object of the invention to produce a handleassembly wherein the handle can be easily assembled to, and disengagedfrom, the remaining members of the assembly.

In the drawing: I Fig. 1 is asectional view through the handle assemblyanda portion of the vehicle body upon which it is mounted. f

Fig. 2 is a section along the line 2- 2 of Fig.1.

Fig. 3 is a detail section of the driving spindle of the windowregulator clutch taken along the line 3-3 of Fig. 4.

Fig. 4 is an end elevation of the drivingmember of the clutch.

Figs. 5 and 6 are details of the retainer or seat for the dog.

Fig. '7 is a fragmentary detail sectional view of the handle.

Fig. 8 is a fragmentary sectional View corresponding to Fig. 1 butshowing a modified form of the handle assembly.

Referring more particularly to the drawing, there is shown an innermetal vehicle body panel I which is covered by trim material 2. Theregulator support plate is designated 3 and the clutch housing, which iswelded or otherwise secured thereto, is designated 4. A coil spring 5 ispositioned over the clutch housing and reacts between the housing andthe trim 2 to maintain the trim 2 and escutcheon 6 outwardly against thehandle I. The handle I is provided with a hub 8 provided with anexternal screw thread 9.

The driving spindle of the clutch is designated l0 and is internallythreaded as at H so that the hub 8 of the handle I can be screwed intothe driving member ID. The driving member ID is joumaled in housing 4which provides a bearing for the driving member ID as at l2. The drivenmember of the clutch is designated [3. The clutch pinion I4 is fixed onthe driven member I3. The pinion I4 is journaled on the support bracket3 as at l5. The driving member ID of the regulator is a die-casting andhas cast therein a steel pintle l6 which is journaled in the pinion l4to provide an additional bearing for the driving member of the clutch.

Although the handle I has a screw fit in the driving member I l it isessential that the handle be locked to the driving member so that itwill not turn out. To this end the hub is provided with a diametricallyextending recess I! in which is pivotally mounted the dog I8. The dog Itis provided with a heel l9 which is pivoted in the socket 20 0f retainer2|. A U-spring22 is positioned between the dog and the bottom wall 23 0fthe recess I1. This spring at all times pivots the dog outwardly intointerengagement with one of the axially extending slots 24 in drivingmember Ill. The handle is also provided with an opening 25 in which ispositioned the plunger 26 having a tapered end 21 which engages thedogl8asat28. I To assemble the handle I in the driving mem-. ber II], theplunger 26', dog l8, spring 22 and retainer 2| are first mounted in thehandle l. Retainer plate 2| is pressed into the recess ll so that itwill retain the dog I8, spring 22 and plunger 26 in the handle. Whileplunger 26 is pushed inwardly of the handle to hold dog l8 in retractedposition, the hub 8 is then screwed into the driving member 10. Afterthe handle has been screwed into the driving member to a suificientdistance so that the escutcheon 6 has a nice fit with the trimming 2,the plunger 26 is released to permit the dog to interengage recess 24.There are six recesses in driving member It) so that handle I has a widerange of rotational adjustment relative to member I0. Recesses 24 act askeepers, any one of which can be interengaged with the dog l8 to lockthe handle on member H).

To remove the handle 1 from member ID it is only necessary to push in onplunger 26 which releases dog [8 from keeper 24 and permits the handleto be screwed out of member In.

In the modified form shown in Fig. 8, instead of a retainer plate 2!,the retainer 30 is formed as an integral part of the die-cast handle I.To assemble this form of the handle the spring 22 is first insertedthrough the mouth 3| of recess l1 and dog I8 is inserted into the recessI! so that the heel l9 pivots on socket 32. The handle 1 is providedwith a hole 33, the outer end of which is closed by escutcheon 6 whenthe handle is in final assembled position on member II].

To assemble the handle on the driving member ID, a pin or wire, or a.similar instrument is passed through hole 33 into contact with dog l8 toretract the same, and. while thus retracted the handle can be screwedinto member l0 whereupon the pin or wire is withdrawn from hole 33 andthe do is forced by spring 22 into interengagement with a keeper 24 inmember 10.

To remove the handle from member ID, the

escutcheon 6 and trimming 2 are first pushed down to uncover hole 33whereupon a pin or wire can be inserted through hole 33 into contactwith dog I8 to release the same preparatory to tuming the handle out ofmember I 0.

I claim:

1. A handle assembly comprising a handle, a rotatable spindle,cooperating means on said spindle and handle whereby the handle issecured to the spindle by rotating the handle relative to the spindle, adiametrically extending re cess in the handle, a spring pressed dogmounted in the recess, a plurality of circumferentially spaced recessesin the spindle one of which is adapted to interengage the dog to lockthe handle the spindle can be rotated by turning said handle in eitherdirection, and a plunger carried by the handle engageable with the dogfor retracting.

the dog preparatory to disconnecting the handle from the spindle.

2. A handle assembly comprising a handle having a threaded hub, aspindle having a threaded opening therein whereby the hub of the handlecan be screwed into the threaded opening in the spindle, a radiallyextending recess in the hub, a pivoted dog in said recess, a spring insaid recess for projecting said dog into interengagement with saidspindle, an axially extending opening in the handle communicating withthe recess, a plunger reciprocably mounted in the axial opening, one endof which engages the dog and the other end of which extends to theoutside of said handle whereby the plungercan be manually depresscd toretract the dog and permit the handle to be turned out of the spindle.

3. A handle assembly comprising a handle member, a rotatable spindlemember, cooperating .15 against turning relative to the spindle wherebytion, the said handle member being provided with a plunger one end ofwhich engages the dog and the other end of which is accessible fromwithout the handle whereby the plunger can be depressed to retract thedog from its keeper to permit the handle to be removed from the spindle.

4. A handle assembly comprising a handle having an externally threadedhub, a rotary spindle havin a threaded openin therein whereby the hub ofthe handle can be screwed into the threaded opening in the spindle, aradially extending recess in the hub, a dog pivoted in said recess on apivot offset from the axis of said hub, a longitudinally extendingrecess in the spindle adapted to interengage the dog to lock the handleagainst turning relative to the spindle, a spring in said first namedrecess for projecting said dog into interengagement with the recess insaid spindle, an opening passing through said handle and communicatingwith said" diametrical recess, said dog having a projection extendinadjacent the inner end of said last mentioned opening whereby said dogcan be disengaged from the recess in the spindle by means of aninstrumentality passing through said last mentioned opening andcontacting said projection on the dog.
